The Fatigue Limit Under Multiaxial Loading

摘要

The further-developed Shear Stress Intensity Hypothesis SIH is presented for the calculation of the fatigue limit of ductile materials under multiaxial loading. The fatigue limit behaviour is analysed with SIH and test results are discussed for different cases of multiaxial loading, especially with the effect of mean stresses, phase difference, frequency difference, and wave forms. In a statistical evaluation, the further-developed SIH provides very good agreement with the experimental results.
